<![CDATA[Benoa Port is the main port in Bali Province and is one of the tuna landing bases in Indonesia with tuna longline fishing gear. The study aims to determine the construction and operating techniques of tuna longline. The results showed that the construction of tuna longline on KM. Perintis Jaya 66 consists of a main line made of monofilament with a length of 30 m, a branch line with a length of 15 meters, a radio buoy line (radio buoy line) with a length of 15 meters made of polyethylene, a buoy line (buoy line) with a length of 10 meters made of polyethylene, a float (float) made of plastic with a total of 84 pieces, fishing gear equipped with a radio buoy that functions to determine the location of the tuna longline when hauling and a fishing hook of the circle hook / J4 type made of stainless steel. The process of lowering the tuna longline fishing gear (setting) starts from 07.00-13.00 and takes 6 hours. The fishing gear is immersed for approximately 10 hours, calculated from the time of the first radio buoy launch. Hauling takes place between 5:00 PM and 6:00 AM ship's time. The vessel operates at a speed of 1-2 knots, following the main line on the starboard side at a 45° angle to the ship's bow. ]]>
